Description

Technical Field

[0001] The utility model belongs to the field of high-frequency transmission probe devices, and particularly relates to a modularly constructed high-frequency transmission probe device. Background Art

[0002] The high-frequency transmission probe device is a test probe device for testing products. In order to facilitate assembly, existing test probe devices mostly adopt a modular setting, that is, after the probe and the base are fixed as a semi-finished product, the semi-finished product is directly assembled with the shell to achieve the purpose of quick installation and convenient maintenance; however, in the existing high-frequency transmission probe device, the probe located at the shell has no positioning structure. After the high-frequency transmission probe device is used for a long time, the probe is prone to deformation, causing its position to shift, thereby affecting the test effect of the high-frequency transmission probe device. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide an anti-deviation modular high-frequency transmission probe device, which can prevent the concentricity deviation of the probe to avoid problems such as mismeasurement and signal interference caused by the concentricity deviation of the probe, thereby making the high-frequency transmission probe device more reliable.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0005] A modular high-frequency transmission probe device with anti-deviated structure, the device includes a high-frequency probe, a base, and a shell. One end of the high-frequency probe is fixedly arranged on the base, and one end of the high-frequency probe passes through one end of the base to be exposed to the outside to form a first connection end. It is characterized in that a mounting cavity passing through both ends of the shell is provided in the shell, a shell positioning portion is provided in the mounting cavity, a probe positioning portion is provided on the high-frequency probe, the shell is arranged at the other end of the base, the other end of the high-frequency probe passes through the mounting cavity to be exposed outside the shell to form a second connection end, and the shell positioning portion is supported on the probe positioning portion.

[0006] In the high-frequency transmission probe device, the high-frequency probe is first installed on the base to form a semi-finished product, and then the semi-finished product is connected to the shell to complete the assembly; based on the fact that one end of the high-frequency probe is fixed on the base, and the shell is supported on the probe positioning part of the high-frequency probe through the shell positioning part, the position of the high-frequency probe is more stable. When the high-frequency transmission probe device is in use, the concentricity of the probe is not easy to deviate, which can effectively avoid problems such as mismeasurement and signal interference caused by the concentricity deviation of the probe, making the high-frequency transmission probe device more reliable.

[0007] Furthermore, a shell positioning groove is provided at one end of the shell, and the shell positioning groove is connected to the connecting cavity. A base boss adapted to the shell positioning groove is provided at the other end of the base. One end of the high-frequency probe passes through the base boss and the base in sequence and is exposed at one end of the base to form the first connecting end. The base boss extends into the shell positioning groove, and the two ends of the probe positioning part are respectively abutted against the shell positioning part and the base boss.

[0008] The arrangement of the base boss and the housing positioning groove allows the housing to be positioned and installed when it is installed on the base, and after installation, the stability of the connection between the housing and the base can be improved.

[0009] Furthermore, the housing positioning portion and the side of the installation cavity together form a positioning channel, and the other end of the high-frequency probe passes through the positioning channel. The setting of the positioning channel can position the other end of the high-frequency probe, making the position of the high-frequency probe more stable.

[0010] Furthermore, the shell and the base are detachably connected via screws.

[0011] Furthermore, the base is provided with threaded holes running through both sides thereof, one end of the high-frequency probe is provided with threads, and one end of the high-frequency probe is detachably mounted to the threaded hole of the base through the threads.

[0012] Furthermore, the number of the high-frequency probes is two or four.

[0013] In the utility model, the beneficial effect of the utility model lies in that one end of the high-frequency probe is fixed on the base, and the shell is supported on the probe positioning part of the high-frequency probe through the shell positioning part, so that the position of the high-frequency probe is more stable. When the high-frequency transmission probe device is in use, the concentricity of the probe is not easy to shift, and the mismeasurement, signal interference and other problems caused by the concentricity shift of the probe can be effectively avoided, so that the high-frequency transmission probe device has better reliability.
